PROBLEM TO BE SOLVED: To provide a seedling transplanter capable of performing turning travel achieving appropriate planting positions and appropriate planting intervals before and after turning.SOLUTION: A seedling transplanter includes: a seedling planting part 4 arranged in a rear part of a travel vehicle body 2, planting a seedling in a field, and capable of being lifted/lowered； a steering member 34 steering and operating the travel vehicle body 2； a steering detection member 34a detecting operation of the steering member 34； and a variation detection member 500 detecting variation in a travel direction of the travel vehicle body 2. The seedling transplanter includes a control device 210 that records a reference value O of the variation detection member 500 when the steering detection member 34a detects start of turning travel of the travel vehicle body 2 by operation of the steering member 34 and that operates a notification member 501 when the travel vehicle body 2 turns and travels and variation in the travel direction of a predetermined value X from the reference value O is detected.SELECTED DRAWING: Figure 23【課題】 旋回前後の苗の植付位置及び植付間隔が適切となる旋回走行が可能な苗移植機を提供する。【解決手段】 走行車体２の後部に圃場に苗を植え付ける苗植付部４を昇降可能に設け、走行車体２を操舵操作する操舵部材３４を設け、操舵部材３４の操作を検知する操舵検知部材３４ａを設けた苗移植機において、走行車体２の進行方向の変化量を検知する変化量検知部材５００を設け、操舵検知部材３４ａが操舵部材３４の操作により走行車体２の旋回走行の開始を検知すると変化量検知部材５００の基準値Ｏを記録すると共に、走行車体２が旋回走行して基準値Ｏから所定値Ｘの進行方向の変化量を検知すると報知部材５０１を作動させる制御装置２１０を設けて構成する。【選択図】図２３
